IMPROVEMENT IN PACKAGES FOR PRESERVING- AND TRANSPORTI'NG BUTTER.

Specification forming part of Letters Patent No. 131,930, dated October 8, 1872.

Be it known that I, EDWARD H. BnNNnRs, of the city of Brooklyn, Kings county, State of New York, have invented certain new and useful Improvements in Packages for Transportation of Butter; and the following is a full and exact description thereof, reference being had to the annexed drawing which forms part of this specification, wherein-- Figure 1 is a sectional view, and Fig. 2 is a top view with the cover removed, showing the inner or supple-mental lid.

A is the outer part. B is the inner part or receptacle. 0 is the surrounding air-tight space. D is'the impervious packing. E is the cover; E the aperture therein having a tube, H. -Fis the supplemental lid; F openings therein, closed by stoppers. braces. 1

The object of this invention is to provide a package for the transportation of butter, and

GG are .with special reference to reuse for an indefinite number of times without injury to the contents.

Butter as now moved to market, deterioratesin warm weath er from twen ty-five to ninety per cent, whether by ordinary transportation or in ice-cars; for, onaccount of the great degree of cold to which it is subjected in such cars, the nature of the butter is changed, and it is rendered so susceptible to heat that it Wilts immediately on exposure to a summer atmosphere, and at once hecomes oily, and soon after rancid. Said icecars, moreover, are not reliable as a means of transportation, as they dependon the use and presence of ice, which, in practice, often gives out and is not replenished, when the butter is ruined, arriving, not seldom, in a melted ordinary vehicles of carriage.

I construct my improved package essentially of two parts-an inner one, to hold the contents to be shipped, and an outer one, to take the brunt of handling. The inner part should be avessel of metal, glass, or glazed ware,

the surface of which is impermeable to oil or water, and readily restored, after use, to perfect cleanliness. The outer part is of wood or any substance not easily broken in handling, and capable of taking without fatal injury, the rough usage incidental to shipment and transportation. tacle for the contents is smaller than the outer part, and leaves more or less of a space between them, which is made impervious, and constitutes an air-chamber for holding a stratum of'air for a non-conductor. It may likewise be filled with some material non-conductive of heat and cold, and lined with paper or felt. The package has a suitable cover formed of two parts, with a like space between, and fitted air-tight to the package.

To provide for trying the butter an aperture is made for the admission of a trier.

This aperture is filled by a tube to preserve .the wholeness of the chamber or air-space,

and the tube isclosed by a stopper, to be removed for the insertion of the trier, and then immediately replaced.

It is desirable in some cases to try the butter at various places in the package, and for this purpose the aperture should be placed in the cover, or in a plate or rim, which may be moved from place to place on thepackage to avoid the necessity of opening it. In such case there would be a number of apertures for the insertion of the trier, all closed air-tight. These may, for safety, be arranged in a supplemental lid, and be so located therein with reference to the opening in the cover, that they may be consecutively reached through a single openin g in the cover. V

The invention isnot confined to special forms or particular materials: Where perfect cleanliness and continued reuse of the package is of paramount importance, the air-space and non -c0nduct0rs may be omitted. made, the package is useful in cold weather,

and has the advantage of holding more pounds as to its dimensions than when made with the surrounding air-space and when made as first before described, it furnishes a better and much cheaper mode of transportation than the icecar, because it may be shipped and moved from place to place Without other protection The inner part or recep- When so 9 mime against ten'iperature, and by any of the ordinary vehicles of carriage.

I claim as my invention- 1. A butter-package for reuse, having an impermeable inner surface of glass, metal, or porcelain, and. an outer protection of wood or any equivalent therefor, substantially as described.

2, In combination therewith, the air-space between theinner and outer parts, for the purposes specified.

3. The apertures, one or more, as described,

in combination with the package, when made with inner and outer parts, with a space between, for the purposes specified.

4. The openings in the supplemental lid, .in combination with the aperture in the cover, arranged and operating'with reference to each other, as described, and for the purpose set forth.
